1) Can you bring your own paint? I know some fields require you to use their field paint, and other charge like an inspection fee if you bring your own. 2) I would like to get into tournament style play, can I play as a walk on?

You bring your own paint no fees, yes you can play walk on the air ball field but probbpy less than other teams since they have full squads

1) yes you can bring your own paint if you bring your own gun. There is no additional fee 2) yes you can

1-yes you can 2-not sure what you mean speedball? You have to ask ref's. Walk on we never got to play it
